52ml humm UNITED STATES PATENT onirica.


To all whom it may concern:

Be it known that I, ELMER A. WILSON, a citizen of the United States, residing at Niles, in the county of Trumbull and State oi Ohio, have invented certain new and useful Inlprovements in Metal Laths and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

y invention relates to metal lathing and is designedl as an improvement upon the type described in Letters Patent No. 408,599

i issued to Ira S. Elkins, on Aug. 6, 1889, and


in Letters Patent No. 459,625 issued to lVal ter V. Bostwick onSept. 15, 1891.

The ob'ect of the present invention is to increase tlle rigidity of the lathing and otherwise improve its construction whereby it Will require a less amount of mortar to adhere thereto. g

The invention consists in taking a piece of metal lathing constructed in accordance with the -Bostwick patent above referred to and cutting a longitudinal slit in the center of each of the projecting loops and then turning the two halves out of the horizontal planes-of said loo s so that they stand nearly 'vertical but slig itly inclined toward each other.l The turning ol' thc halves of the loops in this way adds greatly to the strength ol the lathing while the subdividing of the space left by cuttingr the loop leaves smaller openings to be filled with mortar.

The. invention further 'consists in the fea x tures of construction and combinations of parts hereinafter' described and specified in the claims.

ln the accompanying drawing, illustrating the preferred embodiment olI my invention; lligure- 1 is a perspective viewof a piece of metal lath constructed according to my invention, and Fig. 2 is a transverse sectional View thereof.

Referring more particularly `to the drawing, 1 designates a piece of'sheet metal on which raised loops v2 are formed in rows substantially as described in the patent to Bost- Specification of Letters Patent. Application led September 17, 1908.

Patented Aug. 3, IQQ. Serial No. 453,466A

I wick hereinbefore referred to. Longitlulinal l rid es or corrugations 3 are formed between l an( parallel with the rows of loops as also described in said patent.

A slit 4 is out longitudinally in the center each of the loops and the two halves 5 turned out of the horizontal loops forming a sort oil truss. As illustrated more clearly in Fig. 2; said halves arc preteeablvarranged 'nearly vertical but slightlj.' inclined toward each other so as to be better adapted or'retaining the volenching-tengi1e oi' the mortar and restrict the openings` l whereby the mortar will not be wasted.- l I claim:

1. A metal lath metal formed with a series of )airs ol' parallel slits and having the body ol the. metal be tween the slits of eac-h pan' drawn upward to form loops, each of said loops being slit louh gitudina ly in thevcenter and the two .halves turned out ol the horizontal plane ol' said I loops.

2. A metal lath consisting of a piece ol metal formed-with a series ol pairs of parallel slits and having the body ol' the r'netal between the slits of each pair drawn upward to forni loo s, each ot' said loops being slit longitudinally in the center and the two halves turned torassinne oppositely inclined positionsin a .vertical plane.

. 3. A metal lath consisting of a piece o' C metal formed with a series oll pairs ol parallel slits and having the body ol' the metal beA tween the-slits of each pair drawn upward lo torni loops, each ol" said loops being slit longltudinally in the ycenter and the two halves turnedout of the horizontal plane ol' said loops, and ridges extending' between and parallel with the rows oi' loo is.

.i In testimony' whereof, I aliix niy signature,

in presence of two witnesses.
